Electroencephalography (EEG) acquisition in a wearable form factor is a very important noninvasive solution for long-term brain monitoring. This chapter introduces the basic working principle of scalp EEG measurement, the developing history, and the practical need for personal EEG devices. Conventional EEG systems with passive electrodes are widely used in modern clinical practice. However, they rely on gel electrodes which are not suitable for user-friendly EEG recording. Alternatively, active electrode (AE)-based EEG systems are promising solution for wearable EEG because they are easy to use and compatible with dry electrodes. This chapter summarizes the benefits of AEs and their associated design challenges for medical applications.
